A probe orbiting venus exerts a gravitational force of 2. 58 × 103 n on venus. Venus has a mass of 4. 87 × 1024 kg. The mass of the probe is 655 kilograms. The gravitational constant is 6. 67 × 10-11 n*m2/kg2. To three significant digits, the probe is × 106 m from the center of venus.
Answer:
[tex]\mathrm{9.08 \times 10^6 \:km}[/tex]
Explanation:
To solve for the distance between the probe and the center of Venus, use the formula:
[tex]\mathrm{F = \frac{G\: m1 \:m2}{r^2}}[/tex]
Plugin the values:
G =
[tex]6.67\times10^{-11} \mathrm{\frac{m3}{kg\: s2}}[/tex]
[tex]\mathrm{F} =2.58 \times 10^3\mathrm{N}[/tex]
[tex]\mathrm{m1 = 4.87 \times 10^{24}\:kg}[/tex]
[tex]\mathrm{m2 = 655\: kg}[/tex]
Hence:
[tex]\mathrm{F = \frac{G\: m1 \:m2}{r^2}}[/tex]
[tex]2.58 \times 10^{23} = 6.67 \times 10^{-11} (4.87 \times 10^{24})[/tex]
[tex]\frac{(655)}{r^2}[/tex]
[tex]\mathrm{r = 9.08 \times 10^6 \:km}[/tex]

A tube is being stretched while maintaining its cylindrical shape.
Answer:
This question is incomplete, the complete question is;
A tube is being stretched while maintaining its cylindrical shape. The height is increasing at the rate of 2 millimeters per second. At the instant that the radius of the tube is 6 millimeters, the volume is increasing at the rate of 96π cubic millimeters per second. Which of the following statements about the surface area of the tube is true at this instant? (The volume V of a cylinder with radius r and height h is V=πr2h. The surface area Sof a cylinder, not including the top and bottom of the cylinder, is S=2πrh.)
A) The surface area is increasing at the rate of 28pi square mm per second.
B) The surface area is decreasing at the rate of 28pi square mm per second.
C) The surface area is increasing at the rate if 32pi square mm per second.
D) The surface area is decreasing at the rate of 32pi square mm per second.
Answer:
Surface Area is increasing at the rate of 28π mm²/sec ( Option A )
Explanation:
Given the data in the question;
let r be the radius and h be the height of the tube
so volume V = πr²h
dv/dt = πr² dh/dt + 2nrh dr/dt
⇒ 96n = π × 36 × 2 + 2π × 6h dr/dt
⇒ 24π = 12nh dr/dt ⇒ h.dr/dt = 2
Area Surface S = 2nrh
ds/dt = 2π ( r.dh/dt + h.dr/dt )
= 2π ( 6×2 + 2)
= 2π (14)
= 28π
therefore Surface Area is increasing at the rate of 28π mm²/sec ( Option A )

Read the excerpt from "A Modest Proposal. " Whereas the maintainance of an hundred thousand children, from two years old, and upwards, cannot be computed at less than ten shillings a piece per annum, the nation's stock will be thereby encreased fifty thousand pounds per annum, besides the profit of a new dish, introduced to the tables of all gentlemen of fortune in the kingdom, who have any refinement in taste. And the money will circulate among our selves, the goods being entirely of our own growth and manufacture. Which sentence best paraphrases the excerpt? England will save a great deal of money because they will not have to maintain the cost of raising poor children. The money will circulate amongst themselves. Swift states that wealthy gentlemen with good taste will now have a new dish to buy and consume at mealtimes. Swift argues that caring for thousands of children will cost more than ten shillings a piece each year. His proposal to eat the children would increase the circulation of money by fifty thousand pounds yearly and strengthen England’s economy. Breeding, selling, and eating impoverished children will benefit the people of England in more than one way.

Swift argues that caring for thousands of children will cost more than ten shillings a piece each year. His proposal to eat the children would increase the circulation of money by fifty thousand pounds yearly and strengthen England’s economy.
What is Economy?A complex system of linked trading, consumption, and production activities makes up an economy, and it ultimately decides how resources are distributed among all the players.
The requirements of persons who live and work inside the economy are met by the creation, consumption, and distribution of products and services.
A country, a region, a single industry, or even a family may be represented by an economy. An economy is a collection of interconnected production and consumption processes that ultimately decide how resources are distributed within a community.
Therefore, Swift argues that caring for thousands of children will cost more than ten shillings a piece each year. His proposal to eat the children would increase the circulation of money by fifty thousand pounds yearly and strengthen England’s economy.

What is Civil war?
The American Civil War, commonly referred to by other names, lasted from April 12, 1861, until May 26, 1865. The Union[f] ("the North") and the Confederacy ("the South"), the latter of which was made up of seceding states, engaged in combat.
The conflict over whether to allow slavery to spread into the western regions, creating more slave states, or to forbid it from doing so, which was widely believed to put slavery on the path to eventual extinction, was the main driver of the war.
The election of Abraham Lincoln as president of the United States in 1860 ended years of political contention over slavery because he opposed its spread into the country's western territories.

What is the ratio of the area of ABC to the area of ABD? A. B. C. D.
Answer:
Explanation:
area ABD = 16*12/2
area ABC = 9*12/2
------------------------------
so the ratio of the area ABC to the area of ABD = (9*12/2)/(16*12/2) =
= 9/16
hope this helped!
mark me brainliest :D
The ratio of the area of ABC to the area of ABD is 9/16. The correct option is B.
What is the area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the triangle in a two-dimensional plane is called the area of the triangle.
The area of a triangle is the region bounded by its perimeter or its three sides. The area of a triangle can be calculated using the formula, where the base of the triangle is b and the height is h.
A = ½ (b × h)
The two areas will be calculated as:-
Area ABD = ( 1 / 2 ) x 16 x 12
Area ABC = (1 / 2 ) x 9 x 12
So the ratio of the area ABC to the area of ABD will be
= [ ( 1 / 2) x 16 x 12 ] ÷ [ (1 / 2 ) x 9 x 12 ]
= 9 / 16
Therefore, the area of ABC to the area of ABD is 9/16. The correct option is B.

Answer:
1
Explanation:
The expression that is equivalent to [(2a⁻³b⁴)²/(3a⁵b)⁻²]⁻¹ is;
1/(36a⁴b¹⁰)
The given expression is;[(2a⁻³b⁴)²/(3a⁵b)⁻²]⁻¹
Rewriting this equation gives;[(2a⁻³b⁴)² × (3a⁵b)²]⁻¹
Let us simplify (2a⁻³b⁴)² to get;
4b⁸/a⁶
Similarly for (3a⁵b)²;
⇒ 9a¹⁰b²
Thus, we now have;
[(4b⁸/a⁶) × 9a¹⁰b²]⁻¹
From laws of indices, we know that; x⁵/x³ = x⁽⁵ ⁻ ³⁾ = x²Thus; a¹⁰/a⁶ = a⁴
Similarly b⁸ × b² = b⁽⁸ ⁺ ²⁾ = b¹⁰
Thus, we now have;[(4b⁸/a⁶) × 9a¹⁰b²]⁻¹ = (36a⁴b¹⁰)⁻¹
Finally, we now have;
(36a⁴b¹⁰)⁻¹ = 1/(36a⁴b¹⁰)
